Description:
The surface brightness of the Milky Way (radiated power per unit of
solid angle and per unit of wavelength) is presented for many spectral
regions in the visible and near-visible domain. The catalogue contains
all existing photometries, as far as they cover a major part of the
circumference of our Galaxy. It should be noted that this catalogue is
continuously being expanded. The actual state of the catalogue is
contained in Table 1 of this description, and in the File Summary
below. In Table 2, the Bochum photometries 1-4 are compared to
photometries of other authors employing approximately the same
passbands. Table 3 facilitates the conversion of classical S10-units
into physical fluxes.
NOTE: the B- and V-Photometries will be available in May 1998.
